Is there still a daily limit on new titles?

KDP's Create a Book page now describes weekly limits instead: up to 2 new titles created and 2 submitted per format (ebook, paperback, hardcover) each week. Updates to titles you already submitted don't count.

Can I change my title after publishing?

No. Publish it as a new book, and put 'Previously published as [book title] by [author name]' at the top of the description. Changing both title and author significantly is not allowed.

Can I use a pen name?

Yes, if it is appropriate and consistent across your books. Enter your real name in your KDP account so payments and tax forms are correct.

How do I credit a translator?

Translations must credit both the translator and the original author as contributors. If an older translator is unknown, list the translator as Anonymous.

Checked against Amazon’s pages on 2026-11-09. Not affiliated with Amazon.

What are KDP's rules for book titles, subtitles, series and contributors, and how many titles can I create?

The title must match the cover exactly, and title plus subtitle must stay under 200 characters, with no keyword stuffing, sales-rank or promotional words, unauthorized names or trademarks, or HTML. KDP now limits each account to creating 2 new titles and submitting 2 new titles per format each week, resetting Sunday at 12:00 AM UTC. Title, edition and primary author cannot be changed after publishing.

Title and subtitle

Enter the title exactly as it appears on the cover, and use the same title for the ebook, paperback and hardcover so the formats link on one detail page. Amazon prohibits repeated generic keywords (“notebook”, “journal”, “gifts”), unauthorized references to other titles, authors or trademarks, false suggestions that someone contributed, sales-rank words (“bestselling”), promotional words (“free”), punctuation-only titles, placeholders such as “n/a” or “null”, and HTML. A collection must say so with a word such as “Collection” or “Compilation”. The subtitle follows the same rules. Amazon’s two pages describe the combined limit as “fewer than 200” and “200 characters or less”, so 199 is the safe ceiling. Amazon also notes shoppers tend to skim past titles over 60 characters.

Series

Series books must use a series title that follows the title rules. Public domain and low-content books cannot be added to a series. A new series page appears within 72 hours of its titles going live.

Authors and contributors

The primary author name cannot be changed once the book is published, and anything that isn’t part of the name, such as extra punctuation or HTML, may be rejected. Ebooks take 10 contributors at setup, with more on request; paperbacks allow up to 10, with no exceptions.

Weekly title limits

KDP limits new titles per format each week: up to 2 created and up to 2 submitted for publication. Drafts count when first submitted. The limits apply separately to ebook, paperback and hardcover, and reset every Sunday at 12:00 AM UTC.

Worked example

Planning an ebook, paperback and hardcover of two books in one week fits: 2 ebooks, 2 paperbacks and 2 hardcovers. A third paperback has to wait until the Sunday reset.

Common mistakes

Typos in the author name, which cannot be fixed after publishing.
A different title on the paperback, which stops formats from linking.

Amazon changes these rules; the linked KDP help pages are the authority.
